OpenBSD history and aliases for ksh
Out of the box, OpenBSD doesn’t come with a history file set, so when you logoff your history for that session is lost. Here’s how I set the history file and a few favourite aliases. While we're at it we might as well set the prompt at the same time.
echo "export ENV='$HOME/.kshrc'" >> .profile
echo "export PS1='\u@\h:\w\$ '" >> .profile
Put the following in `.kshrc`
HISTFILE="$HOME/.ksh_history"
HISTSIZE=5000
HISTCONTROL=ignoredups:ignorespace
alias la="ls -la"
alias h=history
alias doas="doas "
